After a water change my 220 gallon tank I tried to plug in my #FX6 #CanisterFilter #aquariumfilter it it won’t start back up I never ran into this problem before I’ve had it running for over a year and a half and I’ve only cleaned it out once or twice i’ve always wondered how to clean and replace the impeller if anything ever went wrong with this filter and honestly I didn’t even know that the impeller and motor was able to be taken off just like life not a day goes by that you don’t learn something new this is what I had to do to get my #220GallonTank back up and running
